How are different sound notes generated in musical instruments like guitar,which uses strings for sound generation ,and flute ,which uses blown air for sound generation ?
Dear Student,
In string instruments like guitars different sound notes are generated due to a simple phenomenon that frequency of a string is inversely proportional to its length.
When we have to produce a sound of higher frequency in a guitar we clamp the string at some extent from the point where we produce vibrations from our fingers.In this way we reduce the length of string and thus the frequency of vibrations increases and thus a sound of higher pitch is produced.
In a flute the phenomenon is same but here the frequency is inversely proportional to the length of air column.
When we close holes of a flute starting from the first hole the length of air column starts increasing and thus the sound frequency is reduced and produces a sound of lower pitch.
Every musical instrument has a set of secondary wave called harmonics . No instrument can have same harmonics
So, all instruments possess a characteristic range of sounds which are unique in their own way.
Regards
